Killer whales can die from ... toothache

According to a new survey published in the journal Archives of Oral Biology, 29 killer whales in captivity in the US and Spain have dental problems.

Like humans, killer whales also have problems with dental disease. Especially in captivity, the incidence of oral diseases increases as whales bite into concrete and steel surfaces in the tank. This is an alarming consequence of capturing this giant fish.

The killer whale is damaged by the lower jaw due to biting concrete and steel surfaces.

In a recent interview, Dr. John Jett of the Stetson University in Florida, the lead author of the study, said: ' Every whale is partially damaged in the teeth. In it, 65% of them suffer from moderate to extreme tooth damage in the lower jaw due to chewing concrete and steel ".

Currently, around 60 world killer whales are kept in 14 parks in 8 different countries to serve human entertainment. Among them, up to 61% of individuals suffer from dental problems .

That caused a wave of controversy in keeping killer whales for human entertainment. However, only France is now following the ban on breeding these giant carnivorous fishes.

The teeth of the killer whale are damaged.

Notably, having dental problems not only caused assassin elephants to writhe, quit eating, but also could 'win' the fish. Because, in captivity, killer whales will lose their immune system and lead to many other diseases after a toothache.
